# Command: job revert
|
|
|
|
The `job revert` command is used to revert a job to a prior version of the
|
|
job. The available versions to revert to can be found using [`job history`]
|
|
command.
|
|
|
|
The revert command will use a Consul token with the following preference:
|
|
first the `-consul-token` flag, then the `$CONSUL_HTTP_TOKEN` environment variable.
|
|
Because the consul token used to [run] the targeted job version was not
|
|
persisted, it must be provided to revert if the targeted job version includes
|
|
Consul Connect enabled services and the Nomad servers were configured to require
|
|
[consul service identity] authentication.
|
|
|
|
The revert command will use a Vault token with the following preference:
|
|
first the `-vault-token` flag, then the `$VAULT_TOKEN` environment variable.
|
|
Because the vault token used to [run] the targeted job version was not
|
|
persisted, it must be provided to revert if the targeted job version includes
|
|
Vault policies and the Nomad servers were configured to require [vault policy]
|
|
authentication.
|
|
|
|
## Usage
|
|
|
|
```plaintext
|
|
nomad job revert [options] <job> <version>
|
|
```
|
|
|
|
The `job revert` command requires two inputs, the job ID and the version of that
|
|
job to revert to.
|
|
|
|
When ACLs are enabled, this command requires a token with the `submit-job`
|
|
and `list-jobs` capabilities for the job's namespace.
|
|
|
|
## General Options
|
|
|
|
@include 'general_options.mdx'
|
|
|
|
## Revert Options
|
|
|
|
- `-detach`: Return immediately instead of monitoring. A new evaluation ID
|
|
will be output, which can be used to examine the evaluation using the
|
|
[eval status] command.
|
|
|
|
- `-consul-token`: If set, the passed Consul token is sent along with the revert
|
|
request to the Nomad servers. This overrides the token found in the
|
|
`$CONSUL_HTTP_TOKEN` environment variable.
|
|
|
|
- `-vault-token`: If set, the passed Vault token is sent along with the revert
|
|
request to the Nomad servers. This overrides the token found in the
|
|
`$VAULT_TOKEN` environment variable.
|
|
|
|
- `-verbose`: Show full information.
|
|
|
|
